Since half-time of the loss at Pittsburgh on Nov. 17, the Detroit Lions quarterback has struggled big time. In that span he’s thrown seven touchdowns and 10 interceptions. Not exactly a good ratio.

Three of the interceptions came in Monday night’s 18-16 loss to the Baltimore Ravens.

It should be no surprise that the Lions are 1-4 in that stretch.

Prior to that Stafford had thrown 21 touchdowns against just seven interceptions. Quite a difference.

Stafford is still No. 1 in Jim Schwartz’s heart just like he has been since the day he was drafted in 2009, first overall.

The Lions coach has not considered making a change, even just a substitution off the bench in the past four and a half games.

“Matt’s our quarterback, he’s going to remain our quarterback and he’s going to play well for us,’’ Schwartz said on Tuesday. “Any time a quarterback struggles, the first thing you look at is it’s all about the team. We haven’t played well enough around him at other times, there’s some times we dropped some passes, there were some times we cut guys loose or got beat in protection. Other times that he can make a little better throw.

“We just need to be better around him — we need to be better blocking, we need to be better catching, we need to be better running the football,’’ Schwartz said. “We do that we support the quarterback. We can play better on defense, we can play better on special teams, we’ll get him back.’’

They’ve only got two more chances to find the old, good Stafford. The Lions play the Giants at Ford Field on Sunday, then the Vikings at Minneapolis on Dec. 29. They need to win both and get some help to get into the playoffs.

If Stafford doesn’t get his mojo back, it won’t likely happen.

Schwartz seemed to bristle when he was questioned if he holds Stafford accountable enough.

“I think we hold all our players to a high standard, but we also don’t publicly shame them,’’ Schwartz said. “We’ve never done that with any player. He’s no different than any other player when it comes to that, that’s just the way it is. He’s our quarterback and he’s going to play well for us. We’re one game down with two to play. There’s a lot of things that can happen over these next two weeks and Matt’s a big part of our ability to be successful.’’

In Monday night’s loss, Stafford seemed to be rushed at times but Schwartz said he could only name one play that he hurried — a screen pass to Joique Bell that was intercepted.

It’s a favorite talk-show radio game in Detroit to second-guess Stafford’s mechanics.

When the quarterback is asked about his mechanics, he tends to roll his eyes and politely answer that it’s not an issue.

Schwartz has been consistent about his quarterback’s mechanics and continued that when asked if perhaps Stafford needs a quarterback guru to help him.

“First of all I think he’s an accurate passer, we have coaches here,’’ Schwartz said. “I don’t know anything about quarterback gurus or anyone else that works with him. I really don’t, I don’t know where a benefit from that would be. Matt’s been a very mechanically sound quarterback and, like I said, we need a better job supporting him.’’

Much has been made of Stafford’s occasional sidearm passes — especially when they’re incomplete.

“That’s just him as a quarterback, he can throw a lot of different ways. It’s just him,’’ Schwartz said. “If a pass isn’t complete, they say well it’s because he threw it sidearm or dropped down into a different slot. That’s also missing the fact that there’s a lot of times when it’s right there. I don’t think it’s any different than when he’s throwing from a traditional in-the-pocket right over the top some of those are going to be right there, some are not.’’

In the past four and a half games, they have not been there.

Schwartz is completely confident he’ll see Stafford from the first nine and a half games return.
